Title: Eddy current type retarder
Inventor: MIYAKE KATSUYA
IPC: H02K49/02
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To double braking force to be generated by fitting, on a rotor, the first conductive cylindrical part which is positioned on the inner periphery side of a ring consisting of the magnet of a stator and the second conductive cylindrical part positioned at the outer periphery part of the ring. SOLUTION: When a stator 7 is set an a braking position by an actuator 9, eddy current is generated at two cylindrical parts 17, 19 of a rotor 11 respectively by the magnetic force of a magnet 5 in the stator 7. When compared with a conventional eddy current type retarder where the cylindrical part mounted on the rotor was single, this device can double braking force working upon the rotor 11 only by modifying the construction of the rotor 11 a little (two cylindrical parts 17, 19 added) without depending upon stronger magnetic force of the magnet 5 fitted on the stator 7. It is thus possible to avoid inconvenience such as an increase in size or weight of a device and double braking force to be generated easily and at a low cost.

Abstract: PROBLEM TO BE SOLVED: To suppress effectively generation of a transmission unnecessary spurious signal without the use of an externally mounted filter, by connecting an orthogonal conversion means and a frequency conversion means and also the frequency conversion means and an amplifier means in a balanced coupling form respectively. SOLUTION: Baseband modulation signals I, Q are orthogonally transformed by an orthogonal transformation device 101, the frequency is converted into an intermediate frequency, and the intermediate frequency signal is converted into a transmission radio frequency by a frequency conversion circuit 103, and an amplifier circuit 105 amplifies the signal to be a required level.
